'50 Shades of Grey' Movie: Niall Horan and...

The 50 Shades of Grey movie favorites for the role of Christian Grey are getting stranger and stranger as fans scour IMDB in search of their dream dom, and now apparently teens are getting in on the 50 Shades casting game.

According to Books & Review, a trio of cherub-faced young stars are actually considered favorites to play Christian. They are Justin Bieber, Zac Efon, and One Direction singer Niall Horan.

Zac might be the least odd of these three options - he's a little older than the other guys, and he's going to have experience filming extremely awkward sex scenes after starring in The Paperboy. Paddles and period sex should seem pretty tame after letting Nicole Kidman pee on him and watching John Cusack pretend to masturbate.

Justin Bieber seems to be a favorite for the role simply because he joked about being cast as Christian Grey during a recent talk show appearance. However, now some fans actually believe that he's the perfect guy to play 15-year-old Christian.

But he'll have some competition. When it comes to young Christian, there could be a Directioners vs. Beliebers casting battle since Niall Horan is apparently another option for the part. To land on the list of favorites, all he had to do was say that he read the first page of 50 Shades of Grey. However, it's hard to imagine Niall getting seduced by older woman Elena when Harry Styles is One Direction's resident cougar-hunter - he'd probably love to play young Christian alongside a hot older actress.

But for now Zac, Niall, and Justin are the three young stars competing for Fifty fans' votes in a Books & Review poll, and they've got some tough competition in Robert Pattinson, Colin Egglesfield, and Alexander Skarsgard. Unsurprisingly, the three older actors are battling it out on top while the three younger guys are trailing far behind (right now Alexander Skarsgard is winning).

So do you think that there's any place for Justin, Zac, or Niall in the 50 Shades movie? Or are feverish Fifty fans just getting a little crazy with their casting picks because they can't stand having to wait for the film?
